Abstract: This project report emphasis enhancement of power quality by using UPQC with fuzzy logic controller (FLC), Artificial Neural Network (ANN) controller and with the conventional proportionalintegral (PI) controller. The unified power quality conditioner (UPQC) is being used as a universal active power conditioning device to mitigate both current and voltage harmonics at a distribution s...

While the unified power quality conditioner based on modular multilevel converter (MMC-UPQC) can be used for recovering of voltage and current in high grids, it is difficult to manage when grid imbalance large. In this paper, a passivity-based control (PBC) combined with sliding mode (SMC) proposed MMC-UPQC improve under unbalance systems. First, according structure MMC-UPQC, equivalent mathema...

In a modern power system, the unified quality conditioner (UPQC) is considered to be most effective device for mitigating problems. The use of dynamic voltage restorer (DVR) active-reactive power-sharing reduces loading on UPQC in all operating conditions, leading better system efficiency and reliability. VA DVC can controlled by maintaining proper angle between load source voltage. this paper,...

Power Quality (PQ) issues have been a major concern as there is increased load demand and usage of variety nonlinear loads. The innovation Flexible AC Transmission System (FACTS) devices great way solving PQ issues. Many like UPFC, D-STATCOM, TCPST are emerging widely used for improvement. In this paper, the Multi Converter Unified Conditioning (MC-UPQC) will be improving in multi-bus systems. ...

The power quality issues are of great concern now a days. The increasing use of power electronic devices based nonlinear loads deteriorate the quality of power. Power electronic appliances are widely used in industrial, commercial and utility system thus leading to various power quality problems. This leads to harmonics being injected into the distribution system and also reactive power burden....

Any electrical power system consists of wide range of electrical, electronic and power electronic equipment in commercial and industrial applications. Since most of the electronic equipment is nonlinear in nature these will induce harmonics in the system, which affect the sensitive loads to be fed from the system. One among the many compensating devices is Unified Power Quality Conditioner (UPQ...
